CHARLES N. GALLAND, OF MINNEAPOLIS, MINNESOTA, ASSIGNOR TO MULTICOLORPRINTING AND MACHINERY COMPANY,

IPORATION OF SOUTH DAKD'IA.

0F MINNEAPOLIS, MINNESOTA, A COR- CYLINDRICAL TYPE-BORDER.

Application filed July 15, 1918.

To all whom it may concern.-

Be it known that I, CHARLES N. GALLAND, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inCylindrical Type-Borders; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has for its object to provide as an improvement inprinting devices a so-called knock-down metallic printing border, and tosuch ends generally stated, the invention consists of the novelconstruction and combinations of parts hereinafter described and definedin the claims.

I11 the accompanying drawings which illustrate the invention, likecharacters indi cate like parts throughout the several views.

Referring to the drawings:

Figure l is a plan view with some parts broken away showing the borderapplied to the cylinder of a press;

Fig. 2 is a fragmentary view showing one corner portion of the printingborder;

Fig. 3 is an enlarged section taken proximately on the line 33 of Fig.1;

Fi 4 is a transverse section taken approx1mately on the line H of Fig.1; and

Fig. 5 is a view corresponding in the line of its section to Fig. 4, butshowing only the printing border.

The cylinder 6 is secured to a shaft 7 shown as equipped with a gear andcertain other devices not necessary for the purposes of this case toconsider. The cylinder is provided with a plurality of longitudinalcircumferentially spaced rows of threaded perforations 8.

A pair of circumferentially spaced longitudinal clamping bars 9 areadjustably secured to the cylinder by screws 10 screwed into certain ofthe perforations 8. For cooperation with the bars 9 a pair of curved endclamping bars 11 are secured to the cylinder by screws 12 that workthrough slots 13 in said bars 11. The slots 13 permit slight adjustmentsof the bars 11 after they are loosely attached to the cylinder.

The cylindrical printing border is made up of a pair of parallelcircumferentially v Specification of Letters Patent.

spaced longitudinally extended printing bars 141 and curved end printingbars 15. At their outer faces, the bars 14: have printing ribs 14preferably of materially less width than the said bars 1 1, but extendedfrom end to end thereof, and likewise, the curved printing bars 1% haveprojecting printing ribs 15. The ribs 1 1* and 15 when inked will printa rectangular border under rotation of the cylinder. The ends of thebars 1% are reduced in width to the width of the printing ribs 14thereof, and these reduced ends are rigidly, but detachably, secured tothe ends of the curved bars 15 by screws 16. The rectangular border thusmade up of the bars 1 1 and 15 is a knock-down structure in which thestraight bars 1 1 may be used with curved bars 15 of different length,or the said curved bars 15 may be used with straight bars 14 ofdifferent lengths, thereby providing an interchangeable element printingborder by the provision of a plurality of the said bars varying inlength.

For holding the printing border on the cylinder, the curved clampingbars 11 and the curved printing bars 15 are formed with interlockingV-shape groove and rib joints 17, best shown in Fig. 3. The clampingbars 9 are simply set up snugly against the straight printing bars 14.The printing border described is adapted to hold in position within it amultiplicity of interlocking type 18, the end members of which areanchored to the curved bars 15 by tongue and groove joints 19. Ofcourse, also printers furniture may be secured in the frame in likemanner.

What I claim is:

1. A cylinder printing border made up of straight side bars and curvedend bars, one of the said end bars having a projecting lock flange andthe other a lock groove for interlocking engagement with interlockingtype or the like.

2. The combination with a cylinder, circumferentially spaced straightclamping bars, cooperating curved end clamping bars and means foradjustably securing said clamping bars on said cylinder, of acylindrioal printing border made up of straight side bars and curvedends bars, the said curved clamping bars and curved printing bars havinginterlocking engagement.

3. The combination With a cylinder, circuinferentially spaced straightclamping hers, eoperating curved end clamping bars means for adjustablysecuring said clamping bars on said cylinder, of a cylindrical printingborder made up of straight side bars and curved end bars; the saidcurved clamping bars and curved printing hersha ving interlockingengagement, and

the'bars of said printing border being de- 10 tachably connected attheir abutting ends.

In testimony whereof I aifix my signature in presence of twu Witnesses;-i i i 7 CHARLES N. GALLAND.
